FITMENT:
Compatible with Scania heavy-duty trucks and buses equipped with SCR (AdBlue/DEF) emission systems, including:

• Scania P Series
• Scania G Series
• Scania R Series
• Scania S Series (New Generation)
• Scania buses/coaches (NGT Euro 6 platforms)
• Some Euro 5/Euro 6 SCR configurations across multiple engine variants

OEM / Cross reference numbers:

• 5WK96755 / 5WK9 6755
• A2C95912900-01 / A2C95912900-02
• 2294291 / 2296801 (Scania OE family references depending on position)
• 5WK97401 (related Continental platform family)

This NOx sensor is used in the SCR exhaust aftertreatment system, measuring nitrogen oxide levels before or after the catalyst depending on installation position.

FUNCTION:

• Measures NOx concentration in diesel exhaust gases
• Sends data to ECU via CAN communication (J1939 system)
• Controls AdBlue dosing strategy
• Monitors SCR catalyst efficiency
• Ensures Euro 5 / Euro 6 emissions compliance

INSTALLATION POSITION:

• SCR inlet or outlet NOx sensor (vehicle dependent)
• Mounted on exhaust line before or after SCR catalyst
• Often used in paired configuration (upstream + downstream)

IMPORTANT NOTE:
Scania NOx sensors like 5WK96755A are part of a shared SCR sensor family, meaning:

• Same physical design across multiple Scania platforms
• Inlet and outlet sensors are NOT interchangeable
• Calibration and software version vary by engine generation
• Correct matching requires OEM number or VIN verification

Incorrect fitment may cause SCR faults, AdBlue errors, or engine derate.

FAQ:

Q1: Is this inlet or outlet sensor?
A1: It can be used as inlet or outlet depending on Scania SCR system configuration.

Q2: What vehicles does it fit?
A2: Scania P, G, R, S series trucks and Scania Euro 5/Euro 6 buses/coaches.

Q3: What are failure symptoms?
A3: SCR warning light, engine derate, AdBlue system faults, NOx sensor error codes, limp mode.

Q4: Are 5WK96755 and A2C95912900-01 the same?
A4: Yes, 5WK96755 is the Continental reference for Scania OEM A2C95912900-01 family.

Q5: Does installation require programming?
A5: Some Scania vehicles require SCR reset or ECU adaptation after replacement.
